Abstract
Un procedimiento para amortiguar ruido audible procedente de un tren de accionamiento de una turbina eólica acoplada con un generador eléctrico, estando causado dicho ruido audible por vibraciones a determinadas velocidades de la turbina eólica a la frecuencia de unos puntos de resonancia acústica de la cadena de accionamiento, comprendiendo el procedimiento: detectar una señal de ruido procedente de la cadena de accionamiento para medir la frecuencia de ruido y la potencia de ruido y procesar la señal de ruido a partir de dicho tren de accionamiento, en el que la señal de ruido tiene una o más frecuencias de ruido de uno o más puntos de resonancia acústica del tren de accionamiento; comprendiendo dicho procesamiento: medir el nivel de presión sonora de la señal de ruido y, solo si dicho nivel se encuentra por encima de un umbral, generar una señal de amortiguación correctiva, en el que dicha señal de amortiguación correctiva tiene un desfase de aproximadamente 90 grados y con una frecuencia o frecuencias aproximadamente iguales a dicha frecuencia o frecuencias de ruido del punto o puntos de resonancia acústica; modular una señal de par de fuerzas con dicha señal de amortiguación correctiva a la frecuencia o frecuencias medidas de la señal de ruido para producir una señal correctiva de par de fuerzas modulada; y aplicar dicha señal correctiva de par de fuerzas modulada a un par de fuerzas de entrehierro de dicho generador eléctrico, reduciendo de este modo dicho ruido audible a dichas velocidades que se corresponden con la frecuencia o frecuencias del punto o puntos de resonancia acústica.
